Cargo test fails on current master

[marvin-bitterlich]

Problem
When I run cargo test on the current master, I get 4 failed tests, that do not fail on ci.

This is the result:

failures:

test result: FAILED. 1850 passed; 4 failed; 3 ignored; 0 measured; 0 filtered out

Steps

1. Use a German windows machine
2. check out the current master
3. run cargo test

Possible Solution(s)

• I am assuming that some of the problems come from string matching with windows error. Those errors seem to be in German on my machine.
